STM32_Programmer_CLI error while flashing internal and external memory from same .srec

Hi everyone,

I'm trying to flash my STM32WB55 and the connected MX25R64 external memory.

I have already created my external loader and tested it with the CubeProgrammer, feeding it with a .srec file containing only external addresses (>= 0x90000000).

However, I was trying to unify the flashing process by using the external loader option present in STM32CubeIDE. This option generates a STM32_Programmer_CLI command and feeds it with a .srec file that covers both external and internal memory:

C:\ST\STM32CubeIDE_1.18.1\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.2.100.202412061334\tools\bin\STM32_Programmer_CLI.exe --connect port=SWD speed=fast mode=UR reset=hwRst --extload <path/to/extloader> --download <pat/to/srec> --verify --log <path/to/log>

srec_info output:

Format: Motorola S-Record
Header: "ST-LINK GDB server"
Execution Start Address: 00000000
Data: 08000000 - 0800013B
08000140 - 08000143
08000150 - 0806F1B9
0806F1BC - 08070535
08070538 - 0807053F
90242000 - 9027EC5B

Here is the output of the command when it fails:

 Can you help me understand what is happening?

Thank you all!

I would like to add that I splitted the .srec in internal and external and then executed the very same command twice, (one for the internal .srec and one for the external .srec), successfully flashing both.

 

So the problem shows up only when I flash the complete .srec
